Hi all - I`m really looking for a helping hand. My setup is an ordinary Z77N - no dedicated graphics card. My final step is getting HD4000 to work on 10.13.6.
Audio works nicely and without the aforementioned popping noises. Thanks for that tip!
I tried all available ig-platform-ids (even more than the 3 recommended by clover drop-down menu). I also followed rehabman's tip in another thread where he hints at digital connectors. No success. Lilu and fixup have been inserted manually in the EFI (other) section. And I installed it additionally via multibeast as other threads recommended doing that without doing anything else. This would get the job done... not for me.
Thank you so much for your help!

Thank you so much for your quick reply. As I am currently reinstalling everything from scratch to have a blank slate, I`m also curious about your "install Clover" entry. How precisely did you install it and which version in particular? Beforehand I was working my way through with a copy of the UniBeast installer (a simple copy of the EFI folder) and not using MultiBeast.

run the clover installer
select custom install : DriverUFEI options : select AptioMemoryFix-64 or OsxAptioFix3Drv (not available in r4586)
* install either AptioMemoryFix-64 or OsxAptioFix3Drv, not both of them

I opted out of APFS conversion because I edited the minstallconfig.xml. I can't tell whether this is relevant for HD4000 to work. But it might do without the ApfsDriverLoader-64.efi? You recommend using Macmini6,2. All the others are talking about iMac14,2. So I will also go for this. Keeping my fingers crossed. And thank you much again for such a detailed answer!!!
*update*
HD4000 works!!! 4000 hugs for you!!!
but... I lost sound despite the fact that AppleALC is in its place...?
*update#2*
got audio back: devices->audio turned it back on with "1"
THANK YOU SOOO MUCH FOR YOUR HELP!!!

Hi itwas,
I'm so sorry - but I hope I may bother you once more. Unfortunately I had to realize new problems. Wifi is gone and both ethernet ports work but are limited to 10 mb/sec. Do you have a remedy for that? TIA!

What WiFi hardware? Z77N-WIFI comes with Intel chipset WiFi card. macOS does not support Intel WiFi chipset, and Ethernet ports are limited to 10 Mb/sec. Do you mean connection speed? Maybe you can check the network cable/switch first.

I didn't swap the WiFi/BT card. I used to have a USB Belkin adapter for BT and WiFi worked out of the box. Now it's back on and working nicely but I haven't changed anything. So WiFi might be called unreliable at best.
But the Ethernet cables are fine. A switch reset plus testing the connections. Is it possible that only one port delivers 1000 Mb (currently both sport 10/11 Mb/sec tops)? I also noticed that restarting is not a wise choice to make. Restarting results in a blurred login screen which triples the image horizontally. A proper shutdown and a cold boot cures that problem.
And again: thank you so much for your dedication!!!
